I bought this case for temporary protection, and I didn't like it very much. It was alright, but the buttons aren't very comfortable to use, and I don't like how the back will sometimes look like if it's wet when the plastic case sticks to the phone. I applied it over my Invisible Shield front/back and noticed peeling on the front protector, though I hadn't allowed my shield to fully set several days before applying this case.
Anoter thing to note: it interferes with the flash. Photos taken with this case while using flash look awful. Seems that in the rush to be one of the first cases on the market, they didn't properly test out how their case functioned.
